Man-machine interface for study of dactylography, has comparing circuit comparing measured value with preset value, and contact activating and inhibiting control of key, when values are same and different, respectively

摘要

The interface has a glove with fingers, where an end of each finger is equipped with an active/passive electrical element (3) e.g. resistor. The element is placed on the key, whose upper surface is provided with another active/passive electrical element e.g. lap of resistors. The key is connected to a unit (8) with a measuring circuit (9). The circuit measures current circulating in the lap of resistors. A comparing circuit compares the measured value with a preset value. A contact (10) activates and inhibits the control of the key, when the values are same and different, respectively.
